The soil-dwelling bacterium Streptomyces achromogenes is the source of streptozocin, also referred to as streptozotocin. It is structurally related to glucose and is a member of the nitrosourea chemical class. Because of its similarity to glucose, it is easier for pancreatic beta cells to absorb and causes a selective buildup in the pancreas. Streptozotocin, also known as streptozocin (INN, USP) (STZ),

In molecular biology, cyanine dye SYBR Safe is utilized as a nucleic acid stain. DNA binds to SYBR Safe. Green light (λmax = 524 nm) is released while blue light (λmax = 509 nm) is absorbed by the resultant DNA-dye combination .Thermo Fisher Scientific, a division of Life Technologies, created the SYBR series of nucleic acid stains, which includes SYBR Safe DNA Gel Stain. The goal was to develop a less hazardous substitute for the widely used DNA stain ethidium bromide, which is known to have mutagenic effects.

A naturally occurring bacterium called Streptomyces hygroscopicus, which is frequently found in soil, produces hygromycin B. The antibiotic is a derivative of the nucleoside adenosine and is categorized as an aminoglycoside. Its unique structure, which consists of a 4-aminoglucose ring linked to a hygromycin A moiety, is what makes it unique.

Polyinosinic-polycytidylic acid, or poly(I:C), is a synthetic substitute for double-stranded RNA (dsRNA). Poly(I:C) is made up of lengthy chains connecting repeating units of cytidine (C) and inosine (I). It is produced in a manner that closely resembles the structure of viral dsRNA, which frequently sets off the immune system's antiviral reaction.

Numerous bacteria, including Streptomyces clavuligerus and Streptomyces lysosuperificus, are producers of tunicamycin. The antibacterial, antiviral, and anticancer properties of tunicamycins, which are naturally occurring nucleoside derivatives, are ascribed to their suppression of enzymatic processes involving polyisoprenyl phosphate and UDP-GlcNAc or UDP-MurNAc-pentapeptide.

Philip Showalter Hench created dexamethasone for the first time in 1957, and it was authorized for use in medicine in 1958. As a steroid hormone belonging to the glucocorticoid class, dexamethasone shares many similarities with the naturally occurring hormone cortisol,
